Assessment of antagonism between lignicolous microorganisms: Research on possible use to preserve wood poles
2010 - IRG/WP 10-10718
Biological environments contain a certain number of microbial populations which, within a given ecological niche, display various relations ranging from symbiosis to parasitism. Researchers have been interested in these types of relations for around fifty years, especially in one very particular type of relationship: the antagonism exerted between individuals of the same microbial population. Toda...

Biodegration of treated wood waste by native fungal communities of tropical soil in French Guiana
2012 - IRG/WP 12-50285
Woods have been protected with fungicides for a long time, and the effects of these fungicides on soil after being leached into the ground have turned out to be a true environmental issue. It is in this perspective that we are proposing to study fungal communities of these contaminated woods in a purpose of bioremediation. Most of precedent studies have focused on ability of some Basidiomycetes an...

Scale-up of a chemical process for copper-based preservative-treated wood wastes recycling
2012 - IRG/WP 12-50286
In recent years, the development of appropriate wood waste disposal options has been encouraged by severe regulations and expensive fees associated with wastes landfilling or burning. An efficient and economically attractive leaching process was developed at laboratory scale (200 mL) for CCA-, ACQ- and CA-treated wood wastes recycling. This leaching process consisted of three leaching steps of 2 h...

Bibliographical study: Decontamination of wood and soils polluted by pesticides used in wood preservation: focus on Bioremediation methods using microbes
2013 - IRG/WP 13-50292
The purpose of this bibliographical study was to seek out the existence of projects (past, present, or future) on soil decontamination in wood treatment plants. Indeed, such polluted soils may contain dioxins and various types of furans. The aim was to find out whether there existed one or more methods bringing into play biodegradation techniques using, for example, species of fungi, yeasts, bacte...

Molecular characterization and biodiversity of wood-decaying fungi in French Guiana
2014 - IRG/WP 14-10825
Fungi from tropical regions are currently under-represented in the classification system. Indeed, difficult access to tropical forests and irregular occurrence carpophores make it complicated to study fungus species in such environments, unlike in European zones where fungal diversity and taxonomy are better known. The purpose of this work was to enhance classification by integrating new data that...
